Expression data from mouse wild-type and Dnmt1-/-Dnmt3a-/-Dnmt3b-/- embryonic stem(ES) cells and nuclear transfer-trophoblastic stem(ntTS) cells, and wild-type trophoblastic stem(TS) cells, primitive endoderm cells, and extra-embryonic endoderm(XEN) cells

ABSTRACT: To investigate the role of DNA methylation in early embryogenesis, we created Dnmt1-/-Dnmt3a-/-Dnmt3b-/- triple knockout (TKO) embryos by the nuclear transfer (NT) technique using TKO ES cells as the nucleus donor, and found that the TKO NT embryos could develop into blastocysts. From the TKO NT blastocysts, we successfully established trophoblastic stem cells (ntTS cells), and these TKO ntTS cells could self-renew and contribute to the placenta in vivo. Expression profile analysis using microarray revealed that, although many genes were aberrantly expressed, the fundamental gene expression patterns of stem cells were retained in these TKO ntTS cells.

Transcription profiling of mouse embryonic stem vs trophoblastic stem cells

Project description:We attempted to identify candidate genes that are expressed more highly in the ICM than in TE cells. Mouse ES cells are cultured from the ICM, whereas mouse TS cells are cultured from the TE. Although these cells have been cultured in vitro, they represent the in vitro equivalents of the ICM and TE. Therefore, genes which are expressed more highly in ES than TS in microarray studies were good candidates for genes predominantly expressed in the ICM in blastocysts.

DNA methylation comparison of ntTS, TS and ES cells

Project description:Placental abnormalities occur frequently in cloned animals. To investigate DNA methylation profile of trophoblast cell lineage of somatic cell nuclear transferred (NT) embryos, we established TS cells from blastocysts produced by NT at the blastocyst stage. Three independent TS cell lines derived from NT embryos rom BDF1 background were used in this study. Two control lines, derived from native blastocysts of BDF1 background, were also used.

Transcription profiling of mouse Rb family triple knock-out (TKO) embryonic stem cells as they differentiate in vivo

Project description:The retinoblastoma cell cycle regulator pRb and the two related proteins p107 and p130 are thought to suppress cancer development both by inhibiting the G1/S transition of the cell cycle in response to growth-arrest signals and by promoting cellular differentiation. Here, we investigated the phenotype of Rb family triple knock-out (TKO) embryonic stem cells as they differentiate in vivo and in culture. Confirming the central role of the Rb gene family in cell cycle progression, TKO mouse embryos did not survive past mid-gestation and differentiating TKO cells displayed increased proliferation and cell death. However, patterning and cell fate determination were largely unaffected in these TKO embryos. Furthermore, a number of TKO cells, including in the neural lineage, were able to exit the cell cycle in G1 and terminally differentiate. This ability of Rb family TKO cells to undergo cell cycle arrest was associated with the repression of target genes for the E2F6 transcription factor, uncovering a pRb-independent control of the G1/S transition of the cell cycle. These results show that the Rb gene family is required for proper embryonic development but is not absolutely essential to induce G1 arrest and differentiation in certain lineages. Experiment Overall Design: Genome-wide gene expression was analyzed for wild-type and TKO ESC and EB cells. Three biological replicates were isolated for wild-type ESCs, TKO ESCs, and wild-type EBs, while five biological replicates were isolated for TKO EBs.

Loss of Tet enzymes compromises proper differentiation of embryonic stem cells

Project description:Tet enzymes (Tet1/2/3) convert 5-methylcytosine (5mC) to 5-hydroxy-methylcytosine (5hmC) and are dynamically expressed in various embryonic and adult cell types. While loss of individual Tet enzymes or combined deficiency of Tet1/2 allows for embryogenesis, the effect of complete loss of Tet activity and 5hmC marks in development is not established. We have generated Tet1/2/3 triple knockout (TKO) mouse embryonic stem cells (ESCs) and examined their developmental potential. Combined deficiency of all three Tets depleted 5hmC and impaired ESC differentiation as seen in poorly differentiated TKO embryoid bodies (EBs) and teratomas. Consistent with impaired differentiation, TKO-ESCs contributed poorly to chimeric embryos and could not support embryonic development. Global gene expression and methylome analyses of TKO-EBs revealed promoter hypermethylation and deregulation of genes implicated in embryonic development and differentiation. These findings suggest a requirement for Tet- and 5hmC-mediated DNA demethylation in proper regulation of gene expression during differentiation of ESCs and development. To quantify global gene expression in differentiating embryoid bodies (EBs) derived from wild type (WT) and Tet triple knockout (TKO), TKO and WT mouse embryonic stem cells (ESCs) were differentiated in vitro to EBs and cultured for 10 days. RNA was extracted using Qiagen RNeasy kit and subjected to microarray analysis. Global gene expression profile of two technical replicas of WT embryoid bodies (2 samples in total) was compared to two technical replicas of two independent TKO embryoid bodies (4 TKO samples in total).

Loss of Tet enzymes compromises proper differentiation of embryonic stem cells

Project description:Tet enzymes (Tet1/2/3) catalyze the conversion of 5-methylcytosine (5mC) to 5-hydroxy-methylcytosine (5hmC) and are dynamically expressed in various embryonic and adult cell types. While loss of individual Tet enzymes or combined deficiency of Tet1/2 allows for embryogenesis, the effect of complete loss of Tet activity and 5hmC marks in development has not been established. To define the role of Tet enzymes and 5hmC in development we have generated Tet1, Tet2 and Tet3 triple knockout (TKO) mouse embryonic stem cells (ESCs) and examined their developmental potential in vitro and in vivo. Combined deficiency of all three Tet enzymes led to complete depletion of 5hmC and impaired ESC differentiation as seen in poorly differentiated TKO embryoid bodies and teratomas. Consistent with impaired differentiation, TKO ES cells exhibited limited contribution to the chimeric embryos and could not support embryonic development in tetraploid complementation assays. Gene expression profiles and genome wide methylome analyses of TKO embryoid bodies revealed promoter hypermethylation and deregulation of genes implicated in embryonic development and differentiation. These findings suggest a requirement for Tet and 5hmC-mediated DNA demethylation in proper regulation of gene expression during differentiation of embryonic stem cells and development. Methylation patterns in tissue samples from a series of wt and Tet1/Tet2 DKO embryos, neonates and adults were generated using ethylated DNA immunoprecipitation with antibodies against 5mC (MeDIP) and 5hmC (hMeDIP) followed by deep sequencing.

Polycomb enables primitive endoderm lineage priming in embryonic stem cells.

Project description:Mouse embryonic stem cells (ESCs), like the blastocyst from which they are derived, contain precursors of the epiblast (Epi) and primitive endoderm (PrEn) lineages. While transient in vivo, these precursor populations readily interconvert in vitro. We show that altered transcription is the driver of these coordinated changes, known as lineage priming, in a process that exploits novel polycomb activities. We find that intragenic levels of the polycomb mark H3K27me3 anti-correlate with changes in transcription, irrespective of the gene's developmental trajectory or identity as a polycomb target. In contrast, promoter proximal H3K27me3 is markedly higher for PrEn priming genes. Consequently, depletion of this modification stimulates the degree to which ESCs are primed towards PrEn when challenged to differentiate, but has little effect on gene expression in self-renewing ESC culture. These observations link polycomb with dynamic changes in transcription and stalled lineage commitment, allowing cells to explore alternative choices prior to a definitive decision.
